Hi all,
Just trying to determine how much the wiring upgrade costs for the average home owner. Please post if you can, the costs and details of the work done.
I am glad I installed a HPWC due to the rapid charging and I put it in the middle of our two car garage in case there is a second Tesla in our future. And if you do have two Teslas then being able to charge in a short period of time will be even more valuable.
When looking for quotes, one electrician said I needed to upgrade 100A -> 150A in order to install a NEMA 14-50 plug. From what I heard, the costs would of been between 8-10k just for hydro to do their work and then probably another few thousand for running a new wire from meter to panel, upgrade panel, install plug etc.. Luckily other electricians said I didn't need to upgrade and they were right, the work is all done now and ESA inspected on 100A.
FYI: depending on what you have running in the house..... IE; stove, dryer, air con..... even if the 3 appliances are running at the same time you are only drawing 72 AMP at one time. I agree that an upgrade would be best but truth be told, you could run another 40 or 50 amp breaker and only use it, say, at night and make sure you're not running the oven at the same time. you would be fine, a 100 amp service can draw 100 amps. it's the next stage of breakers that requires a 20 % threshold for continuous draw.... 50 amp breaker = 40 amp continuous.
That's quite expensive. I'm paying approx $2000 for a full upgraded 200amp panel (100amp currently), plus a 70-80 foot metal conduit/power run to the garage to the HPWC Tesla unit located in between both sides in case of 2 Teslas eventually. This includes city shut down, all fees and re inspection for ESA approval. 2k seems like a decent amount given the panel upgrade is about $1300 anyway.
Love seeing the advice of non electricians....
To put it short every job and house is different. In Toronto 200A upgrades can run from $ 1500 to $ 3000. The cost of the HPWC varies greatly on the distance from you panel to the charger location. Rough rule of thumb is at 100A budget $ 20-30/ft with a minimum $400 if the charger is the only thing they are installing. Minimum permit cost in Ontario is $ 100 from the electrician (not cost but what is charged to the customer).
Did the 100amp -> 200amp upgrade involve completely replacing your existing panel?
in my case, I had a 200amp line into my meter but only 100amp into the house.
The electrician basically installed a 200amp panel ahead of my 100amp bloc in the basement.
I feel the $1700 was a good price.
